Chown

Is there a way in WHM or cpanel to change the ownership of a file?
I need to change the ownership of some scripts that I edited in notepad, and uploaded with cPanel File Manager.
This appears to have caused a problem. I was told that it may be the reason the compiler/ interpreter is writing to my script files. And that I need to chown it to the "owner".

If not, if someone could give me a hint as to where to start, I would be grateful.
